I'm not exactly "meh", more like I wasn't very shocked and didn't feel like it was as impactful as it could have been if there was someone else in Moeka's shoes. She was the lab member with least importance IMO. I pretty much figured that SERN would come for them pretty early on. When Okabe started getting those texts and they magically got connected to SERN at a full level it was obvious. Plus you all were talking about "the first half being build up and second half starting at 12 becoming the real deal"
Don't get me wrong, I love the show and it's superb. One of my best watches, and I'm only half way through. But I wasn't that surprised, that's all. Maybe it's because I had some time to think about the series since I only watched a few episodes per day.
